2 Claims.

The invention hereinafter described is an improvement in smoking pipe structures and relates more particularly to smoking pipes having a tobacco stoking arrangement forming a part thereof.

The present invention is a continuation in part of the invention shown and described in my copending application Serial 258,060, filed February 23, 1939.

It is the principal object of the present invention to provide a smoking pipe structure having a tobacco stoking means incorporated therein, which pipe structure may be economically produced.

A further object of the present invention is to provide a pipe smoking structure having an arrangement for controlling the ring of tobacco therein, which structure can be quicmy and simply assembled or disassembled, as desired.

` A further important object of the present invention is to be provide a smoking pipe structure so arranged as to permit the user thereof to control the amount of oxygen being supplied to the tobacco being consumed and, at the same time, providing a relatively cool passage for the smoke from said consumed tobacco to the mouth of the user thereof.

Another object of the present invention is to provide a smoking pipe structure wherein the smoke from the tobacco being consumed is drawn away by suction on the mouthpiece, without passing through the remaining body of the tobacco within the pipe.

Further objects of the present invention will be pointed out in the accompanying drawing and the following detailed description thereon and still further objects will be obvious from a consideration thereof.

In the accompanying drawing:

Fig. l is a side elevation of a pipe structure comprising the present invention having a broken away section for viewing the interior of a portion thereof. f

Fig. 5 is a further enlarged detail top cross sec- (Gl. lh-181) tional view of said bowl portion of the pipe but is taken on line 5--5 of Fig. 2.

Fig. 6 is an enlarged side View of a tubular member forming a part of the present pipe structure and having a portion thereof broken away to show its interior or bore, and

Fig. 7 is a top cross sectional View of said tubular member taken on line l-l of Fig. 6.

Referring now more particularly to the accompanying drawing wherein like reference characters designate similar members of the present invention, reference numeral l refers to a pipe mouthpiece having a longitudinal bore 2 formed therethrough from end to end thereof, while numeral 3 designates a stepped end portion of said mouthpiece l having threads formed upon the periphery thereof. The threads of the periphery of stepped portion 3 are shown in engagement with threads formed upon the interior face of stern portion ii, which stem portion li is formed as a part of a bowl 5.

The bowl 5 may be formed, by way of example, from natural prier-wood, meerschaum and like bowl-forming materials, or may also be molded from 1prier-wood or meerschaum compositions. Said bowl 5 has a bore 3 formed in the top end portion thereof, which bore tapers outwardly as at l into an enlarged chamber 6, while the opposite end of said bowl has an opening i6 formed therethrough which opens into said chamber 6 and is substantially' in line with bore 8. Chamber 6 is connected with the interior or bore of stem portion l and is thereby connected to the longi- -tudinal bore 2 of the mouthpiece t. Further, chamber 6 has a series of projections i! formed therewith and extending therefrom.

Inserted and mounted through opening E6 and having a tight but detachable t with the wall thereof is a tubular member i2 which is preferably formed from a lightweight metal, as by way of example, aluminum. The lower end of tubular member l2 has an annular fiange l5 formed therewith and extending perpendicular thereto. Said flange l5 is substantially disc-shaped due to a centrally located opening 33 formed therethrough. The opposite or upper end of tubular member l2 has the top edge E3 thereof tapered, that is, slanting from the bore downwardly towards the periphery thereof. The bore of tubular member l2 is substantially decagonal. from cross sectional view, as shown in Fig. 7 of the drawing, due to the said bore being formed by a series of walls lll which are angularly joined to one another.

A coating 3i of either carbon or meerschaum is positioned upon the exterior face of tubular member l2. This coating is applied thereto by painting either a liquid carbon or a meerschaum paste upon the exterior face of said member and thereby providing both a protective coating for the metallic surface of the tubular member as well as a moisture-absorbing member within the smoke passage of the pipe structure. In this manner, the smoke is ltered and at the same time, assured of passage through the pipe structure without direct contact with metal, thereby preventing the presentation tol the user of` a of the bore of section 2i and, likewise, the diameters of sections 2l, 22, 23 and 2t are respectively substantially equivalent to the diameters ci the bores of sections 22, 23, T24 and 25. Sections 2t, 2|, 22, 23 and 24 have lefthand threads 23 formed upon the peripheries thereof with the bottom portions of said peripheries formed blank as at 3l. The bores of sections 2l', 22, 23, 251 and 25 have lefthand threads 29 formed upon the upper portion of the face thereof, which threads 2Q Vare in engagement with said threads 23, thereby threadedly engaging the sections one with the other. Section 25 has an annular flange 26 extending perpendicularly therefrom which is mounted upon flange l and retains section 25 with its connected sections within the tubular member I2. The portion of section 25 extending outwardly from opening 33 has righthand threads 2l formed upon a periphery thereof to which is screwed a cap 30, which cap prevents the inward movement of section 25 and closes the lower end of the bore of section 25 and the other sections when in their nestled position, as shown in Fig. 3, but at thesame time, cooperates with flange 26 to permit section 25 to be rotatably supported at4 all times by flange l5.

Said nest of telescopic sections are connected to one another by inserting the section of the smallest diameter through the lower end of the next larger section until the threads 28 and E@ thereof are in engagement and said next larger section is inserted through the lower end of the bore of its next larger section and this procedure is carried out until all oi the sections are mounted within the bore of section 25. At this time', section 2li is screwed within the projecting portion i9 of a disc il, thereby connecting said disc H to the telescopic sections. Disc il has a series of angularly joined walls i3 formed upon the edge thereof giving it a decagcnal peripheral configuration similar to the cross sectional configuration. of the bore of tubular member l2. As best shown in Fig. 3, said disc Il has attached' thereto a meerschaum cap 32 covering the upper face of the disc.

In assembling the present pipe structure, tubular member l2 is inserted within opening l5 of bowl 5 until flange l5 contacts the outer face of bowl 5 and thereby prevents the further insertion of the tubular member l2 within chamber 6 and tapered portion v'5. lDuring the insertion of tubular member l2 Within opening l,

the upper portion of the tubular member will also be inserted past the ends of the series of projections '9 and will thereby be retained in a spaced relation from the wall of chamber and slanting portion 1. lTapered edge I3 of tubular member I 2 will form a passageway with the wall of tapered portion 'l and will be assisted in maintaining this passageway due to flange l5 and projections 9. The passageway between edge i3 and the wall of tapered portion 1 can be formed narrow in order to prevent tobacco from sliding therein while, at the same time, readily permitting the passage of smoke therethrough.

The nest of telescopic sections and disc I1 can be inserted within the bore 8 of the bowl 5 downwardly into and within tubular member I2 until flange 28 of section 25 contacts the inner face of flange l5 of tubular member l2, at which time the cap 3B, by a right hand rotation thereof, is screwed onto the section 25 for retaining the same and its connected members within tubular member i2. It is obvious that the nest of sections and disc ll can. be inserted within chamber 6, by way of either bore 8 or opening l', before the insertion therein of tubular member l2 or disc ll' and the telescopic sections can be inserted with tubular member l2. By va reversal of the foregoing procedure, the members can be rapidly and readily disassembled for cleaning or like attention.

Vlfhen it is found desirable, any suitable filter il may be placed within the bore of Ystem portion for remo-ving the heavy oils, tars and moistures from the tobacco smoke passing through said bore to the bore of mouthpiece i.

In operating the present device, after the same has been assembled, the user thereof should place within the bore of tubular member l2 and bore 8 of bowl 5, both bores of which are in line with one another, tobacco suflicient to ll the bore of tubular member i2 above cap 32 up to and above bore 8. By giving cap 3Q a right hand rotation, section 25 will be rotated,

as will sections 2li, 23, 22 and 2l, but section45 2;@ will be caused to remain non-rotatable due to the socketlike engagement of walls lli with the decagonal edge of disc Il, whose series of walls i8 are sized and shaped to slidel longitudinally but not laterally of walls It and the frictional engagement of tubular member l2 with the wall of opening it. Due to the non-rotation of section 2E), the remaining sections will unscrew one from the other and thereby rise 1ongitudinally of tubular member l2. The user of the present pipe will, according to his particular taste, determine by experience the position at which he desires the burning portion of the tobacco lil to be positioned within or above the bore 8 of bowl 5. After the determination of such a point, the burning portion of tobacco may be kept at that position by rotating member 3@ and thereby elevating disc ll and the tobacco supported thereon. The position of the burning tobacco within the bore 8 or thereabove determines the amount of oxygen which is to be supplied thereto and it has been found by experience that the tobacco burns equally as well above the bore 8, as shown in Fig. 2, or within the bore 8, whichever may be desirable.

The user of the pipe structure, by drawing through bore 2 and applying the flame to the tobacco within bore 8, will cause the ignition thereof, due to the air drawn through bore it, past tapered section l, chamber 6v and the bore of stem portion 4.

The projections 9 are spaced '-75 apart to provide an opening therebetween for the passage of the smoke.

Due to the meerschaum cap 32, disc l1 can be elevated up to the top of tubular member l2 and the tobacco thereby consumed down to the cap 32. Said cap 32, being absorbent and heat insulating, will prevent the disc I'i from sticking to the walls I@ of tubular member l2, inasmuch as the tars and residues from the burnt tobacco are completely absorbed by the cap 32. Further, tubular member I2 being formed from a lightweight metal, will remain cool due to the protection of cap 32 and the tobacco thereon and will therefore readily conduct heat from the smoke by the periphery thereof.

The pipe structure as herein described and shown upon the accompanyingr drawing is capable of considerable modification but, however, any such modifications as come within the scope of the appended claims are deemed to be a part of the present invention.
